4. Please show the plants for the biofilter. Refer to section 3.11 -20 of VSMH.
5. Please show the cleanouts on biofilter.
6. Please show the SWM notes /detail from the approved plan WP0200600050- Northown Phase 1. This
detail I/S 11 describes the offsite improvements for adequate downstream channel.
Sincerely,
